BZIP2 compression extremely slow

https://discuss.gradle.org/t/bzip2-compression-extremely-slow/16738

I am working on migrating an Ant-based project to Gradle, and one sticking point is that the distTar task with compression = Compression.BZIP2 set is 5x slower than the equivalent Ant task.

Is this a known issue? Is there a good fix or workaround?

Edit: For a workaround, having Gradle make an uncompressed .tar and then bzipping with Ant speeds things up immensely:

distTar.compression = Compression.NONE
distTar.doLast {
ant.bzip2(src: distTar.archivePath, destfile: "${distTar.archivePath}.bz2")
delete distTar.archivePath // optional
}
